Portfolio Manager (Energy market BESS)

Giga Storage was founded in 2018 and has grown into a market leader in large-scale battery energy storage. We develop, build, and operate utility-scale BESS projects and are actively expanding across Northern Europe, with projects in the Netherlands, Belgium, and Germany. With a growing pipeline of up to 2 GW, significant financial stakes and a direct impact on the energy transition are at the core of everything we do.

For our Energy Desk in Amsterdam, we are looking for a Portfolio Manager who will take the lead and structurally elevate our commercial performance.

What will you do?

As a Portfolio Manager, you operate at the commercial heart of our organization. You are the strategic and analytical driving force behind the Energy Desk. You carry full P&L responsibility for GIGA’s operational BESS portfolio and play a key role in smart, forward-looking contracting of our growing asset base. Your goal: maximize revenues, manage risks, and consistently outperform market expectations.

You will work closely with colleagues from Route-to-Market Origination, Implementation & Contract Management, and Asset Operations. You act as the connecting link, making the financial impact of operational decisions transparent to the Management Team and our investors.

You carry P&L responsibility for GIGA’s operational BESS portfolio across the Netherlands, Belgium, and Germany. This portfolio represents tens of millions in revenue in its first year and is expected to grow significantly as more assets become operational.

This role is not just about managing an existing portfolio. You will play a key role in building the commercial and operational foundation of our Energy Desk. As we are scaling rapidly, you will help shape how we operate, contract, and optimize our assets going forward. This makes it a unique opportunity to join at an early stage and have a direct impact on how the Energy Desk is set up.

Your responsibilities include:

• Portfolio oversight and full P&L ownership of the GIGA asset portfolio

• Developing short- and mid-term portfolio strategies with a three-year horizon

• Building in-house benchmarks to challenge external optimizers

• Defining market and trading strategies across energy and flexibility markets

• Monitoring contractual obligations under all RtM contracts

• Performing scenario analyses and identifying risks

• Leading Trading/Portfolio Committee meetings

You report directly to the Head of Energy Desk.

What do you bring?

• At least 5 years of experience in the energy sector, including a minimum of 2 years on an energy desk at an optimizer or utility

• In-depth knowledge of energy and flexibility markets: day-ahead, intraday, imbalance, FCR, aFRR

• Strong analytical skills and proven experience with modeling

• A completed degree in economics, engineering, or a quantitative field

• A proactive, entrepreneurial mindset and comfort in a fast-growing environment

• The ability to challenge both internal and external stakeholders

• You are fluent in English; Dutch is not required but considered a plus

Why Giga Storage?

At Giga Storage, you are in the driver’s seat. You take direct P&L responsibility for one of the largest BESS portfolios in Europe, operated by one of the leading players in the market. This is a high-impact role with a high degree of autonomy, where you are responsible for driving the commercial performance of a rapidly expanding multi-country portfolio.

At the same time, you will work in an organization where things get done. Short lines of communication, a high level of autonomy, and a team with an open culture. Not a rigid corporate structure, but a dynamic scale-up where your insights matter and where you help shape the strategy.

This role is based in Amsterdam. We work in a hybrid setup, where you are expected to be present in the office at least three days per week
